The answer is 45 and 81. To find it out you need to use double algebra. 1. (x+y)-(x-y)=90 x-x=0 y+y=2y/2= 1y=y 90/2= 45 y=45 2. (x+y)+(x-y)=162 y-y=0 x+x=2x 2x/2= 1x=x 162/2=81 3. check your work x+y-x-y=90 81+45-81-45=90- x+y+x-y+=162 81+45+81-45=162 81+45= 126 81-45=36 126+36=162 That is how you find the answer.
First, you have to know the difference between Prime Numbers and Composite Numbers. Prime Numbers are numbers that has only two factors: 1 and itself. Composite Numbers are numbers that have factors other than 1 and itself. Composite numbers are always even, with only one exception: number 2. Two is the ONLY EVEN PRIME NUMBER. Never will you encounter another even prime number because it will always have AT LEAST 3 factors. # ITSELF. # ONE. # TWO. Now that we know the difference between Prime and Composite, we can answer your question. 4,567,278 is an even number. It is divisible by itself, one, two and probably more numbers. Therefore, it is COMPOSITE!
Two isotopes of an element have the same atomic number (number of protons) but have different mass numbers (sum of protons and neutrons). This means that they will differ in the number of neutrons despite being the same element.
It is not the sum of two things, but only the number of protons found in the nucleus of the atom. The atomic mass is the total number of neutrons and protons in the nucleus.
Given the following approximate radii for Earth and mars orbits: Earth = 149,598,261 km Mars = 227,939,150 km The shortest distance between the two is the difference between the two, which yields 4minutes 21seconds for radio to go that distance. The longest distance between the two is the sum, which yields 21minutes.
The sum of Protons and neutrons
The numbers are 98 and 64
65 + 97 = 162 97 - 65 = 162 The two numbers are therefore 65 and 97.
The difference of two numbers is 8. Their sum is 22. What are the two numbers?
It is 162.
90
the sum of two whole numbers are 77 .their difference is 48.what are the two numbers
Two numbers with a sum of 4 and a difference of 9 are -6.5 and 2.5.
Difference. A sum is the result of adding two numbers, and a difference is the result of subtracting two numbers.
